“…Statistical methods, such as MRA, SPSS, together with ANNs, are conducted to predict TBM performance [58,59]. For the penetration rate of TBM, the prediction accuracy of SVM, LMRA, and ANN are compared [60,61]. In order to predict the penetration rate and advance rate of TBM, Armaghani et al utilized an ANN, PSO-ANN, and ICA-ANN to make the prediction and compared the prediction ability of these methods [30,39].…”
